vulkanupload: honor downstream pool allocation parameters

Browse source 
If a downstream buffer pool is offered, vulkanupload checks its allocation
parameters to honor them. Only adds to usage the TRANSFER bits, which are
required to upload buffers.

Also, fail if the buffer pool cannot be configured with the current parameters.
